[PATCH] pata_of_platform: remove direct dependency on OF_IRQ

[Rob Herring]

From: Rob Herring <rob.herring at calxeda.com>

CONFIG_OF_IRQ is not available on some platforms and using of_irq_*
breaks the build. Since resources are already populated in the platform
device, get the irq from there instead.
